Yes, its accurate - I think that pic is from a microsoft slide.

10gbs both ways is by no means a bottleneck. I don't feel like explaining now, so maybe someone else can pick things up.

Both systems have their share of problems and flaws in their designs.

You don't have to explain (to me, now, at least) why 10.8gbs is not a bottleneck; but you certainly do have to explain why, if it is not, 20gbs/15gbs is a bottleneck in the PS3. That just doesn't seem to make any sense at all.

Who said the speed between the CPU and GPU was a bottleneck in the PS3?

256bit split bus in the RSX, ring connector in cell, RSX to XDRAM - those are some of the potential bottlenecks in the PS3 I was talking about.

Xbox 360: 512 RAM-->(22.4 GB/s)-->GPU;
and 512 RAM-->(22.4 GB/s)-->GPU-->(10.8 GB/s)-->CPU
OTHER WAY
GPU-->(22.4 GB/s)-->512 RAM
CPU-->(10.8 GB/s)-->GPU-->(22.4 GB/s)-->512 RAM

Considering the CPU and GPU share the same bus, any bandwidth the CPU uses limits the bandwidth available to the GPU. So for example if the CPU is using 10 GB per second, there´s only 12.4 GB per second bandwidth left for the GPU.
